Quaife LSD was my very first mod 4 yrs ago. Best mod to the 335i no doubt.
M3 rear toe links don't fit non-M cars.
I don't know that M3 toe links are stiffer than RE or other aftermarket links anyway. A few M3 track drivers have switched out their toe links for aftermarket.

yes, you are right about the M3 toe arms. However there are 2 other sets of arms from the M3's rear that fit in our car. That combined with M3 rear subframe bushings should help a ton:

Great review, thanks for posting. I also had the Rogue toe links installed recently to compliment my M3 suspension and Quaife LSD; it all works wonderfully together. I feel confident putting down power now, no more moving around in the rear. The rear end in these cars squirms around noticeably without the M3 subframe bushings and the toe links.

Next step for me is coilovers to eliminate the squat/dive that occurs under acceleration/deceleration. Then a tune.

^ Any increase in NVH with RE toe links or did you install them at the same time as the M3 components?
Sounds like a wise path to improve traction and susp prior to a tune

I had the M3 subframe bushings/front & rear sways/Quaife LSD all done at the same time. No difference in noise. Rear end still squirmed a bit though.

Then I had all the other parts of the M3 suspension installed (full list in my garage) and the Rogue toe arms. Love the feel of pushing the gas pedal now. Haven't put more than 15 miles on it since then so I don't have an opinion on NVH (even though it was weeks ago -work keeps me on the road), I'll report back if I notice anything.

I just can't see adding power when the car isn't setup to handle it in the first place!

The faint clunking sound I noticed almost right away after installing these toe links has gotten worse. Finally got around to putting the car on a lift today to check all bolts of recently replaced suspension components and they're all properly torqued. I can move RE toe links around with my hand due to those shitty spherical bearings! Gotta get with HPA and/or RE and see what the warranty is on these things. Granted CA roads aren't good like Nevada's, but I'm not a pothole or bump magnet by any means. These things should hold up for more than 3 months

Both RE and HPA don't warranty the spherical joints. They are considered a wear item like brake pads. Replacement cost is $30. ea. per joint. Three months service life is terrible Anyone who wants these arms can have them when I replace them next month w/a part that functions properly on a street driven car.

According to HPA, I'm the first customer to have this problem with the RE toe arms. Lucky me I guess According to an engineer, this is bound to happen with spherical joints on a street driven car. VM toe arms had the same problem. Shouldn't happen after 3 months, and I shouldn't have to pay for replacement parts that soon
